Summorum Pontificum itself foresaw a report, in order to adjust any issues with implementation -- and the report now obtained was generally positive. As Montagna reports:
The previously undisclosed text, which forms a crucial part of the official report by the Congregation for the Doctrine of the Faith on its 2020 consultation of bishops concerning Summorum Pontificum, reveals that “the majority of bishops who responded to the questionnaire stated that making legislative changes to Summorum Pontificum would cause more harm than good.”
The overall assessment directly contradicts, therefore, the stated rationale for imposing Traditionis Custodes and raises serious questions about its credibility. [source]
We all knew that the report was probably more positive than negative, because we all could see with our own eyes the very positive developments on the ground: greater reverence, an increase in respect in the celebration of the Novus Ordo, and the gradual end of the painful separation between Catholics now living in the same parish. There were negative issues, as it happens with any human endeavor, but they were far outweighed by the positive aspects.
Since the report was the basis of the limitations (and plan of gradual extinction of the Traditional Latin Mass) established by Francis' document Traditionis Custodes, ghost-written by radical liturgist Andrea Grillo for Francis, we know that the document itself, in addition to being doctrinally illegitimate (since it claims to extinguish what no pope can extinguish), is also procedurally illegitimate and inept. Based on lies, deceptions, no wonder it is a purely evil document.
